According to Joseph Robinette Biden, the so-called Equal Rights Amendment — which is not, nor has it ever been, ratified per the terms of Article V — is now the 28th Amendment to the United States Constitution.

Or so he’s declared . . . via tweet and a jazzy infographic. Voilà!

Is that a power of his under Article II? It’s amazing, really, because I’ve actually sat down and read the Constitution — has, umm, Joe Biden? — and I’m struggling to find the clause wherein it states that the president has the power to declare via social-media post that the Constitution has been amended. Just like that! Lickety-split!

I have to admit, however, it’s really quite fortunate that when the Founding Fathers, meeting in Independence Hall in Philadelphia in the summer of 1787, framed the Constitution, they remembered to include the almost-forgotten proviso that the president could change the basic law of the land via Twitter three days before the end of his term. Good thing that James Madison and friends hadn’t accidentally assumed that MySpace would survive as America’s primary social-media platform!

But we shouldn’t be surprised that the Democrats are trying to pull this stuff, should we?

The Democrats — also known as the “rule of law party,” according to no one but them — are the party of Barack Obama’s pen and phone.

The Democrats are the party that believes that an amendment that reads “A well regulated Militia, being necessary to the security of a free State, the right of the people to keep and bear Arms, shall not be infringed” doesn’t actually mean that the right of the people to keep and bear arms shall not be infringed.

Joe Biden’s Democrats insist that the 14th Amendment — or maybe it’s the Fourth Amendment? Wait, actually, is it the Ninth Amendment? — unambiguously grants the people a constitutional right to an abortion.

The Democrats, as a party, believe when the First Amendment says that “Congress shall make no law respecting an establishment of religion, or prohibiting the free exercise thereof; or abridging the freedom of speech, or of the press” that applies completely . . . unless someone has used “hate speech” on the Internet, or prayed the Lord’s Prayer at the 50-yard line before kickoff, or decided to voice the scientific fact that young men can’t turn themselves into young women or vice versa no matter how hard they may try.

“A Republic, if you can keep it,” Ben Franklin told us. Or, rather, “unless Joe Biden tweets something out on Friday.”
